Quantum PX500 Series tape libraries
Put another way, the PX500 Series "is attractive because you can start really small and get really, really big," said one judge. "You won't need a crane to add things in."
The PX502, which is the smallest of the three tape libraries, is a 4U box with one or two drives. It holds either 32 DLT or 38 LTO tape cartridges, and can mix media. Next up in size is the PX506, which can hold 88 DLT or 100 LTO cartridges. The PX510 goes up to 40U, and can hold 22 drives and 220 cartridges.
